Javascript Dijit form horizontalSlider仅第一次加载？

我使用dojo脚本创建图表，使用dijit滑块进行缩放和平移。第一次滑块加载正确，但第二次（从另一页返回后）图表加载正确，但这些滑块除外。使用Jquery进行事件处理。刷新页面后，工作正常

第一次使用CSS时

<table>

        <tr>
        <td class="pad" align="center">ZOOM X(<span id="scaleXValue">1</span></td></tr>
        <tr>

这是第二次

<table>
    <tbody><tr><td class="pad" align="center">ZOOM X(<span id="scaleXValue">1</span>)</td></tr>
    <tr><td>
            <div id="scaleXSlider" data-dojo-type="dijit/form/HorizontalSlider" value="1" minimum="1" maximum="5" discretevalues="6" showbuttons="false" style="width: 450px;">
            </div>
    </td></tr></table>

缩放X（1）

所有css类都不是第二次加载的。您能帮助我：（.

Dojo跟踪它通过指定id创建的对象/小部件。如果您在具有相同id的对象上再次运行解析器，Dojo会尝试创建第二个实例，但已经有一个，因此它应该在js控制台中抛出错误

在再次解析同一页面之前，请先销毁创建的小部件/对象ID。在这里，我已将“小部件”声明为全局变量，因此，如果存在任何小部件ID，请在解析之前销毁它们

if(widgets){
    widgets.forEach(function(widget) {
    widget.destroyRecursive();
});
}
widgets =  dojo.parser.parse();

这对我有用
